A spillway water system comprising at least one adjustable barrier sluice gate of one watercourse and defining: one upstream stretch and one downstream stretch of the watercourse arranged upstream and downstream of the sluice gate respectively; one spillway point arranged at a spillway height and at which a spillway water flow rate skims which flows from the upstream stretch and flows into the downstream stretch; the sluice gate comprising adjustment device/unit adapted to raise or lower the spillway height; a first measurement device/unit for measuring the level of water flowing along the downstream stretch; a second measurement device/unit for measuring the level of water of the upstream stretch; and a command device/unit of the adjustment device/unit operatively connected to the first and to the second measurement device/unit and configured to raise or lower the spillway height depending on the level measured by the first and the second measurement device/unit.

A growing unit for biological hydrosynthesis, energy generation and storage and/or topsoil restoration, the growing unit comprising: a container configured for growing plants and containing a growth media located therein; a reservoir located in a lower portion of the container and associated with an outlet portion of the container, and a substantially vertical liquid inlet pipe associated with the reservoir, wherein the growth media comprises a mixture including a first catalyst, wherein the first catalyst stimulates formation of a humified soil and wherein the growth media is amended with an irrigation liquid which stimulates biological activity in the growth media and in and adjacent to the reservoir.

A hydroelectric power generation system using channel for water supply includes a water guidance unit, a one-way gate, and a plurality of power generation units. The water guidance unit includes a channel for water input, with an entrance provided in front of the channel for connection with a water source. The water entering the channel passes through the one-way gate and is prevented from flowing back to toward the entrance, so as to be effectively accumulated. When the water in the water guidance unit reaches the predetermined water level, the power generation units around the water guidance unit conducts power generation with the water, thereby improving the power generation effectiveness.

A water reservoir system for generating, accumulating, storing, and releasing electrical energy comprises a reservoir wall built in a shallow body of water such as a sea or an ocean with a height exceeding the outside water level by about 10-25 m, thereby defining an interior of the water reservoir. Excess electrical energy from other renewable sources of electricity such as wind, solar power, or supplied by a local power grid is used to operate water pumps to fill the interior of the water reservoir with water during times of peak supply of electricity. Water is drained from the water reservoir to the outside body of water and generates electrical energy by flowing over a plurality of water turbines, thereby generating electricity and supplementing electrical power for the local power grid during times of high demand. Additional interior sources of renewable energy may be used to supplement external sources of electrical power in operating the system of the invention.

A sluice gate for a hydropower station, a method of operating a sluice gate and a hydropower station. The sluice gate includes rollers via which the sluice gate can be movably mounted on rails and a sealing surface having a seal with which an upstream water can be sealed off from a downstream water. Lubricant lines are provided through which lubricant can be fed to the rollers and lubricant return lines are connected to the rollers. Via the lubricant return lines, used lubricant can be guided from the rollers to one or more collection locations in order to be able to collect and properly dispose of used lubricant.

This invention describes the electrical power generation in a sustainable way, by means of a device, which is installed in the downpipes of rainwater collected by the building roofs, capable of transforming the potential energy present in said rainwater runoff into electrical power, where the generated energy is stored in batteries or fed into the utility network.

An energy generating system includes a dam in an estuary defining a water containment area. The dam includes a plurality of dam elements, each including a plurality of dam panels hingedly connected in series, which are urgeable from an inoperative folded state in a chamber to an operative state by a corresponding pair of main or secondary buoyancy tanks as the tide rises and falls. Each pair of main buoyancy tanks with the corresponding dam element defines a water race within which a water wheel is located. The water wheels are mounted on corresponding drive shafts which are connected in series and which are rotatably carried on support frameworks which are supported on the main buoyancy tanks. Electricity generators are supported on carrier frameworks which are supported on the secondary buoyancy tanks at respective ends of the dam, and are driven by the adjacent one of the drive shafts.
